From 5efa314e711b24e80ff36d5baa24f995ea07d359 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Fix a scoping issue with "no autodie" and the "system" sub
Don't queue nonexisting subs for reinstalling later when
exiting the 'no autodie' scope.
FIXME: if the original sub 'can be undef for "CORE::" subs', does this
break for those? Is that the case when $symbol =~ /::/, as guarded for
on L566?
Bug: https://github.com/pjf/autodie/issues/69
